f Whenithe curtain rod is being installed, the .trigger 'is .dropped-tothe position shown'in' Figs. 2 and 4 afterthe rods have been spreadVsufficiently. to freely receive thew'find 0Wy carsi Figs. 2 and f4 thatthe portion 21rthereof will i@ i i ing and the rods are then telescopedtogether against the casing as shown in Fig. 1, the inclined faces ofthe teeth 15 riding past the hook 18 and forcing it outwardly. The hook16 will snap back into each depression between the teeth as each toothis passed and when enoughpressure has been placed on the rod, the pawlwill automatically lock the rod sections in engagement. In other Words,the teeth 15 are saw-tooth shaped so that .the pawl will ride over theteeth when the curtain rod sections are travelingv into telescopingengagement but will lock to prevent the rod sections traveling out oftele-' 15 scoping engagement. g

-By'providing the trigger in the form of a loop 'with the plane of theportion 21, at Y right angles to the plane of the loop, thetrigger willlockitself in theposition showinA in 20 Fig. 4. This occurs because thepressure of thelap l16 against'the portion 21 opposes the initialraising of the trigger, the portion 21 having slightly passed deadcenter in reaching its Fig.. 4 position.V @The rods A and B include theend arms 22 Vand 23, respectively, the former being attached to j awmembers 24'provided with teeth v25toengage the casing. Y

The auxiliary curtain bracket 26 has the Aarm 27 to be received in theopen end of the larm 22 and an arm 28 to be received in the open end ofthe arm 23. A fingerY 29 on the arm 28 extends through ak slot 30 in thearm 23and'locks the rod B securely in engagement with the arm 26. Theadvantage of this construction lies the fact that the bracket 26 is heldin place 'bythe engagement with the casing 10 while the rod Bmay beremoved from its brackets without disturbing the rod A. Y- Some changesmay be made'in the construction and arrangement of the parts of myinvention without departing from the s real Vspiritand purpose of myinvention, and it ismy lintention to Vcover by my claims Iany `modifiedforms of structure or use ofl niechanical equivalents, which may bereasonably included within their scope.

I claim as my invention: i j 1'. Ina curtain rod, a pair vof rodmembers, one 'ofwhich'telescopes within the other, a 'plurality' 'oflsaw-tooth shaped teeth formed 'on one rod member, a pawl attached tothe`other rod member and provided with axfre'e end terminating in a hookextending through said other rod member and positioned to en- ,fgage on'e of said teeth and a trigger member having a portion of greater widththan thickness interposed between the pawl and the adjacent wall of therod member to which itis secured, said trigger member being capable ofAjmo'vementto'rotate said interposed portion "-fr'om'a position whereinit holds the pawlA out ''f engagement with Isaid teeth to va positionwhere it allows the pawl to ride against the teeth. Y

2. In a curtain rod, a pair of telescoping rod members, a plurality ofteeth Jformed in the wall of one rod member, a pawl rigidly secured atone end to the other rod member and provided with a hook at its free endprojecting 'through an opening in said other rod member, said hook beingpositioned to engage cneof said teeth andthe pawl being of springmaterial' and mounted to normally urge said hook into said engagementand a trigger in- Vcludiiig a portion interposed between said pawl and arod wall to which it is attached, said portion being of greater widthand thickness andthe trigger ,being movable to rotate said portion froma position wherein it holds the pawl in an'inoperative position to aposition where the pawl may Vengage said teeth.

3. In a curtain rod, a pair of telescoping ,.85 rod members, a pluralityof teeth formed in the wall of one rod member, a pawl rigidly securedVat one end Ato the'othervrod member and provided with a hook at its freeend projecting through an opening in said other rod `.o member, saidhook being positioned to engage one of said teeth and the pawl being ofspring material and mounted to normally urge said hook into saidengagement and means for holding the pawl out of engagement with g5 saidteeth, said means'being movable to a position vallowing the Vpawl toengage the teeth. v Y

4. In a curtain rod, a pair of telescoping rod members, a plural-ity ofteeth formed in the 10o wall 'of 'one rod member, a pawl rigidly securedlatjoiie end to the other rod member and provided with a hook at itsfree end projecting through an opening in said other rod member, saidhook bei-ng positioned t'o engage :.105 one of said teeth and the pawlbeing of spring materialF and mounted to normally urge said hook into'said engagement and a loop shaped trigger including a portion ofgreater width and thickness interposed between the p'awlrno and the wallto which it is secured, the remainder of the loop being positioned in aplane substantially perpendicular to the plane of said portion.

-v5. In a curtain rod, apair of telescoping 5115 rod members,.aplurality of saw-tooth shaped teeth formed, in the wall of one of therod members, afpawl rigidly secured at oneend to the wall `of theotherlrod member vand proi vided Yat its free YendJ a hook .projectingf'120 .through an opening in said other rod member wall and adapted tovengff'f'e one of said-teeth, the pawl being otspring material andnormally urging said hook into' engagement with a, tooth and a triggerincluding a por- 125 tin of greater width'and thickness interposedbetween the'pawlandthe wall'to which it is attached, the trigger being'adapted to be moved to :rotate saidp'ortion from a position holding the'away' from 'the teeth to a 5130 position where it does not interferewith the engagement of the hook with the teeth.

6, In a curtain rod, a pair of telescoping rod members, a plurality ofteeth'ormed in one rod member, a pawl attached at one end to they otherrod member and yhaving a free end capable of movementtoward and Iawayfrom said teeth and adapted to engage oneA of said teeth and a triggerincluding a portion of greater width and thickness and interposedbetween said pawl and thewall to` which it is attached, the triggerbeing adapt'- ed to be moved from a positionwhere said portion holds thepawl away from yContact with the teeth to a position Where ity does notinterfere with the contact of the pawl with the teeth. g c

7. In a curtain rod, a pair of telescoping rod members, a plurality ofteeth formed in one rod member, a pawl attached at one end to the otherrod member andV having a free end capable of movement toward yand awayfrom said teeth and adapted to engage one of said teeth and means `tohold the pawl in an inoperative' position,- said means'being movable toa position where it does notinterfere with the engagement` of the pawlwith the teeth.

8. In a curtain rod, a pair of telescoping rodv members, a plurality ofsaw-tooth shaped teeth formed in the wall of onerod. i

member, pawl of lspring material secured at Vone end to the Wall of theother rod member and free at its other end to move from a positionengaging said teeth to a position out of engagement with said teeth anda trigger f including al portion of greater widthy and thicknessinterposed between the pawl and the wall to which it is secured, saidtrigger being movable from -a position wherein the* pawlengages one ofsaid' teeth to a position wherein the pawl is out of engagement with anyof said teeth.
